In the event of a mechanical breakdown in a narrow channel or fairway :
-
Signal for help
-
Anchor the vessel
-
Move to the starboard side of the channel and anchor
Correct Answer
A. Move to the starboard side of the channel and anchorExplanation
In the event of a mechanical breakdown in a narrow channel or fairway, the best course of action is to move to the starboard side of the channel and anchor. This helps to ensure that the vessel is out of the way of other passing vessels and reduces the risk of collision or obstruction in the channel. Anchoring also helps to maintain the vessel's position and prevent it from drifting further into the channel. By moving to the starboard side, the vessel allows sufficient space for other vessels to pass safely on the port side.Rate this question:

In a heavy sea to prevent swamping , you should _______.:
-
Stop the engines
-
Let go the anchor
-
Use the engines and stem the waves and the seas
-
Fill the boat with water to make it ride better
Correct Answer
A. Use the engines and stem the waves and the seasExplanation
To prevent swamping in a heavy sea, the best course of action is to use the engines and stem the waves and the seas. This means using the power of the engines to navigate through the waves and seas in a controlled manner, rather than being at the mercy of the rough conditions. This allows the boat to maintain stability and avoid being overwhelmed by the water, reducing the risk of swamping. Stopping the engines or letting go the anchor may not provide enough control or stability in such conditions, while filling the boat with water would only make the situation worse.Rate this question:

3 prolonged blast at intervals of not more than 2 minutes.
Correct Answer
A. 2 prolonged blasts at intervals of not more than 2 minutes.Explanation
When a power-driven vessel is "underway" but not making way, meaning it is not moving through the water due to engine failure or other reasons, it must sound two prolonged blasts at intervals of not more than 2 minutes. This signal alerts other vessels in the area of the vessel's presence and indicates that it is not able to maneuver as expected.Rate this question:
